X Prize dangles $10 million for fuel-sipping car
The X Prize Foundation, best known for sponsoring space travel competitions, on Thursday offered $10 million to make a super-efficient car.
At the New York International Auto Show, the foundation and sponsor Progressive Casualty Insurance announced the newly named Progressive Insurance Automotive X Prize. The competition, open to both established automakers and unknown engineers, is meant to result in "real cars" that are available for purchase, rather than concept cars.
